Step by step

Download Poky

Why SVN if Poky already moved to GIT, you may ask. Well, we feel fond of that revision because we know it to work. Feel free try Poky's GIT or a newer SVN revision. In fact, you might want to take a look at Poky OMAP too.

Configure

Fine tune

With newer kernels exmap complains about missing headers. For now, you can have the rest of the profiling tools by taking exmap-console and exmap-server out of "RDEPENDS_task-poky-tools-profile" in $POKY/meta/packages/tasks/task-poky-tools.bb. This is needed for a Sato image.

The kernel and u-boot can be copied to the boot partition on your MMC/SD card. Take the image tarball and untar it in the root partition of your MMC/SD card; also, untar the modules tarball on the root of your file system.

Recipes

What are the most important recipes around here? Here's a list of them.

U-boot

A recipe for u-boot can be found here: $POKY/meta/packages/uboot/u-boot-omap3_git.bb. This comes from Poky. You can try with another recipe for u-boot as long as it works on the Beagle. See $POKY/meta-texasinstruments/conf/machine/beagleboard.conf if you want to change it.

Kernel

Kernel recipe is $POKY/meta-texasinstruments/packages/linux/linux-beagle_git.bb. This kernel, kindly forked by Felipec, is currently based on 2.6.28-omap1, with dspbridge patches on them. This is the GIT repository for it, see under the tidspbridge-stable branch: http://github.com/felipec/linux-omap/tree/tidspbridge-stable/.

Bridge library

The API for accessing the Bridge driver is provided by this recipe: $POKY/meta-texasinstruments/packages/tidspbridge/tidspbridge-lib_git.bb. The code is taken from this GIT repository: http://git.omapzoom.org/?p=platform/hardware/ti/omap3.git. Of course, it requires the DSP Bridge driver, which is provided by the kernel.

TI's OpenMAX IL

The recipe for building TI's OpenMAX IL is located here: $POKY//meta-texasinstruments/packages/tiopenmax/tiopenmax_0.3.5.bb. This code is rather old. The goal is to use this GIT repository for OpenMAX: http://git.omapzoom.org/?p=platform/hardware/ti/omx.git, but that'll be later.

GStreamer plug-ins

Two sets of plug-ins can be used: gst-openmax and gst-goo. Both are included in the GStreamer task. Recipes for these are located here:
